What is crystal field splitting, and why is [Co(NH3)6]3+ diamagnetic?
Coordination Compounds
Original Khojo Papers practice question — not from a past board paper.
Ionisation isomers give different ions in solution because a ligand and the counter ion are interchanged, as in [Co(NH3)5SO4]Br and [Co(NH3)5Br]SO4. Linkage isomers differ in which atom of an ambidentate ligand is bonded to the metal, as in the nitrito and nitro isomers of [Co(NH3)5NO2]2+.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Coordination and hydrate isomerism are two further kinds of structural isomerism.
